Takeshi Minamino won the vacated championship on September 9th, 2004 in a 3 way match. The current status of the Title is unclear as Minamino only defended the title once since winning it.
In February of 2010, Negro Casas appeared on CMLL's Ras de Lona show (19 minute mark), mentioning this championship as one of the ones he currently held. The belt, only briefly shown, appeared to be the second version of this title. It's unclear how Negro Casas came to have this belt, and he has no known defenses. To avoid setting a troubling precedent, Negro Casas will not officially be listed as champion until someone explains how he won the belt, or he actually defends the championship.
History of Championship
Championship Confusion
Championship reigns previously noted for Filoso, Osamu Namiguchi and Katushiko Nakajima are believed to actually been promoted as WWA World Junior Light Heavyweight Championship matches, not using the actual belt or championship lineage. See that title for more information.
